This is the much ancient deadmoo OS X 10.4 leak. This is the first publicly available version of OS X Tiger for x86. It's an installed virtual raw disk image that was made using the 8B1025 build of 10.4.1. This build uses a BIOS based loader, making the entire Hackintosh project possible.
For people who don't remember the deadmoo/curtus password is bovinity
You can run this on Qemu with flags something like this:
qemu-system-x86_64.exe -m 512 -hda tiger-x86-flat.vmdk -net nic,model=rtl8139 -net user -no-acpi -no-reboot -k en-us
Press F8 at the loader and type in
platform=x86pc -v
You can get it to run on other emulators as well.
I've found removing the AppleTPMACPI.kext helps speed things along.
